Just because a large audience would see your game, does not translate to a large audience playing your game. You have rather nieche topics. Worse. You do not go full nieche, but are inbetween. I do not know how your game play is, but that is my two cents about your game's appeal.
It is like making a clown game, but the clowns only have a red nose. It won't appeal to people disliking clowns, and clown enthusiasts will complain about the lack of big shoes, green wigs, and makeup. Of course there are people that like a little bit of clowning, but in my opinion those are fewer than the other two groups.
But looking at your patreon numbers and follower count, you are doing quite well for an itch game with what looks like ai created art (it does not matter how you really create those. It looks ai at first glance and people do not bother to watch any videos or explanations how it might not be the usual ai).
You might have done worse by trying to appeal to the two larger groups - there are just so many games
